The only reason why people buy bitcoin, is to make money. I believe in the tech, its the future blah blah blah. Your here to make "sick" gains, most will not have the stomach for it. How many investors bought 100 btc for $100 and sold them at $20,000 each, practically none.
Say bitcoin reaches $1 million and you invested now at $3800. You honestly think you wont sell when it hits $50,000 or any other figure that will improve your life significantly. Nobody knows if, when or how it will happen.
Don't waste your life waiting for a win, you will end up going crazy. Invest yeah sure, check it once a week / month on progress and just let it be man. For all we know, it could be outlawed and crash to $0 tomorrow.
You have a point. Market are so volatile and we don't know what the tommorow may bring but if you have a lot of courage and can take all the risk,i'm sure you will wait until you see the value will high too much ti gain more profit. But it is also good the idea that you said.
